To all whomv it may concern:

Be it known that I, FRANK KNNEY, a'

citizen of 4the United States, residing at Troutdale, in the county of Multnomah' and State of Oregon, have invented cert-ain new and useful Improvementsin Injector Vacuum-Producers, of which the following is a specification.

The present invention pertains to an im;v provement 1n vacuum producing apparatusl A and especially to a ,form of devicel by means is provided with suitable screw threads, and j interior 1a conforming Vlargestat the' center, approaching aspheri- Fig. 2 is a longitudinal vertical sectional Fig. 3 is a detail of a' 4'shows'a modifica-- view of F ig.j1. clamp support. Fig. tion of a splash board. Referring tothe drawings in detail, 1

designates an expanded or bowl-shaped member consisting of -a casing of the usual tube or pipe material, though it may be made of wood, brass: or any desired material. The tothe exterior, is

.cal form and converges to. a comparatively small aperture,-at what may be termed the forward lend. `The interior of this aperture the exterior is adapted .toreceive the clamp collar 4, which is lheld thereon by the screw bolt 5, the collar having formed integrally therewith the legs'lt upon which the device is supported. A

At the upper side of the bowl 1y isformed an intake 11, which is provided with the 'usual linterna-l screw threads, in `which 'is engaged the union 10 toy which is attached the water supply pipe .9. Illntering 'the large end of the bowl is .a similar screw threaded aperturel adapted to receive-the union 121 'to'which is attached the hose pipe .13. Within the-aperture at the small end ofthe bowl is secured, by means of the usual maintained 1n a horizontal et is to arrange a `system of.l nanner that a stream o f. therein, so as to drlve' screw threads, the tube 3 whose interior opening Sa'expands from said point of connectlon to its` outer end, terminating in enlarged spherical opening 15a ofthe re ceptacle' or catch-basin 15. 'The lower sid@ of the catch-basin lis left open and the side walls are extended downwardly to form supportv 6, which has a length equal to that of legse. At suitable intervals about f rim of theI base 6 is provided a number of openings 16 to permit the outflow of the :water coming from the tubes 9 and 3. Un

der this construction thez device may position, and mayfbe placed in a sink, or in any suitable place where the water passing through it maybe conductedaway.

Depending from theintake 11 and formed :integrally therewith, is. a semicircular or crescent-shaped tube 2, which leads to the center of the bowl and inclines towardits smaller-fend, terminating within the aperture ofthe `outlet tube, but leaving a small exterior-space. This crescent or semicirculartube begins with 'the same diameter .as diminishes to a small 'the inlet. tube -11 and orifice 2?.

The water entering from pipe 9 will'be compressed into the converging orifice 2v 'and will be caused to emerge with vgreat force, entering the tube 3 which at its smaller end is of substantially the same diameter. as the outlet end of the orifice' 2.

and completely filling itsv contracted portion at the beginning, driving the air from the bowl 1 and exhausting that in pipe 13;

thereby making it a powerful suction pipe,

theexpansion of tube 3 augmenting this effect. AsA the water exp'ands'into the basin 15 its. force becomes exhausted and it 'emerges quietly through.. the openings 1 6,

where it may be conducted away in any convenient manner. A splash ,board '7 formed in the casingof basin' 15 and is inclined forwardly in front of the opening of -tube 3, upon which the stream is projected and its force is thereby further dissipated before-leaving the tubing.

In Fig. 4 is seen a modified form of splash board 7"; mounted on the transverse shaft 18, .in front of the lower edge of vtube Y3.:

This board is inclined upwardly and outvwardly against the side of the basin, with its extremity 7" inclined toward the tube.

In the outer wall of the basin is arranged a set screw 17, which bears against lthe .'in. removingfchlst lfrom carpets, rugs and,

splash boa-rd, and by means of which'the.

lattermay be adjusted bach; and forth, as may be' necessary to control the. force of Water coming through.
